A Living Will is a document signed by you that directs your doctor that you do not want life-sustaining treatments or procedures to prolong your life if you are in a terminal condition. Because it takes effect while you are still alive, it is called a Living Will. Life-sustaining treatments are procedures that will not cure your terminal illness, but rather prolong dying. For example, respirators, kidney dialysis and CPR may be considered life-sustaining treatments. Provisions of nourishment and pain medication are generally not covered. The requirements for the consent and witnessing procedures vary somewhat from state to state so it is important that your Living Will comply with applicable state law. Health care providers and relatives may be prohibited from being witnesses.
